[jira] [Created] (IGNITE-17791) SQL: Allow index scans for different but compatible types

Aleksey Plekhanov created IGNITE-17791:
------------------------------------------

             Summary: SQL: Allow index scans for different but compatible types
                 Key: IGNITE-17791
                 URL: https://issues.apache.org/jira/browse/IGNITE-17791
             Project: Ignite
          Issue Type: Bug
            Reporter: Aleksey Plekhanov
            Assignee: Aleksey Plekhanov


After IGNITE-17027, index scans for different types (when indexes type should be converted to search row type) are prohibited. It is correct for incompatible types (with different comparison rules, for example for INT and VARCHAR), but for compatible types, we can support such a scans.

For example, if indexed type is INT and search row type is BIGINT we should allow index scan despite the fact that BIGINT is type with higher priority.
